IMPROVEMENT IN SOFT-METAL HAMMERS.

Specification forming part of Letters Patent No. 146,989, dated February3, 1874; application tiled December 3l, 1873.

To all whom fit may oncern:

Be it known that I, JEHIEL C. GOBURN, of the city and county ofl/Vorcester and State of Massachusetts, have invented a certain new anduseful improvement, viz., a Soft- Metal Hammer; and I hereby declare thefollowing to be a full, clear, and eXact description of my invention,sufficient to enable other skilled artisans to make and use the same,reference being had to t-he accompanying drawings, which forma part ofthis specitication, and in which- Figurel represents a side view of asoftmetal hammer made in accordance with my invention. Fig. 2 representsa central longitudinalsection of the same at line x x, Fig. l; and Fig.3 represents a transverse section at line w fw, Fig. 1.

This invention relates to an improved manner ot' preparing babbitt-metaland similar soft lnetal for market; and consists in casting the metalinto the form of amallet or hammer, with the handle and head entire in asingle piece, the handle being re-ent'orced or stren gthcned by a rod ofsteel or iron through its center, as hereinafter described.

In the drawing, A denotes the head, and B the handle, both otl which arecast in a single piece, and at the same time, in a mold ot' properJr'orm, a bar or rod, C, of iron or steel, being iirst placed in themold in such position that it will form a central core to the handle B,as shown, extending from the front of the head to the rear end of thehandle. Portions of the bar may be flattened, as indicated at c c, toprevent the ba-r from being drawn out or becoming loose when the hammeris put to severe use 5 also, when cooling, the metal contracts and hugsclosely around the bar, so that said bar is very firmly bedded andsecured in place. The bar C renders the handle B very stift and strong,and prevents it from bending or breaking at its junction with the headA.

The metal put up in these hammers is sold in place of the ordinaryingots or pigs, and, when the hammers have become battered or broken,can, as pigs, be melted up for other uses. The cost ot' the metal whenput up in this manner is not necessarily greater than when sold inordinary-shaped pigs, so that the shops can be furnished with goodsoft-metal hammers at a very little or no extra expense over the cest oftheir metal when furnished in the ordinary form. It will thus be seenthat, without detraetin g in the least from the value of the pig metal,it is made additionally useful at no appreciable additional expense.

Il y making the handle Vand head in a single piece, the cost of a woodhandle, which would otherwise'be needed, is saved, while the weight ofmetal as a pig is greater than with simply a head.

I-Iaving described my invention, what I claim therein as new, and desireto secure by Letters `Patent, as au improved article of manufacture,

A soft-metal pig formed as a mallet or hainmer, the head and handlebeing cast in one piece, and re-entorced 0r strengthened by the rod C,substantially as herein set forth.
